Abstract

The cover is of the grating or rectangular slab form (2) with a series of transverse slots (3) permitting effluent passage, and peripheral underside bearing surface (6) which makes a smaller angle with the vertical external surface of the gutter than the seat does, thus producing a virtual knife edge support (8) with better stabilized bedding of the cover on its support. A cover edge is split up into alternate lengths with the slope in the opposed senses (6 or 6'), and the slope is in directions normal to the cover edge.
